All models of the PosiTest AT-A meet Accuracy Class 1 – recommended for precise applications on construction sites, in laboratories and industry. PosiTest AT-A gages far exceed the requirements.
Competitors' devices often only achieve the inferior Class 2.
| Model | Typical Application Area | Accuracy Class DIN 51220 |
|---|---|---|
| PosiTest AT-A 20 mm | Standard tests according to ISO 4624 | Class 1 ★ |
| PosiTest AT-A 50 mm | Universal use, larger test surfaces | Class 1 ★ |
| PosiTest AT-A 50C | Concrete, Screed, ZTV-ING, EN 1542 | Class 1 ★ |
| PosiTest AT-A 50T | Tile adhesive, EN 12004-2 | Class 1 ★ |
Note
:
Devices of
Accuracy Class 1 significantly surpass those of Class 2 in terms of precision and standard-compliant
application.
Devices with Class 2 achieve only ±2 % deviation – that is only half as good as our PosiTest AT-A models!
| Criterion | Class 1 (recommended, as more accurate) | Class 2 |
|---|---|---|
| Relative measurement deviation | ±1.0 % | ±2.0 % |
| Hysteresis deviation | ≤ 0.5 % | ≤ 1.0 % |
| Repeatability | ≤ 0.5 % | ≤ 1.0 % |
| Traceable calibration | Required | Required |
| Application | Standard laboratories, construction sites, quality assurance | Simple field tests |
| Standard basis | DIN 51220 | DIN 51220 |
There are classes 00, 0.5, 1, 2, etc., where smaller numbers mean higher accuracy .
